When the data are arranged in numerical order, the median is the middle value – or the mean of the two middle values – in a set of data.

Practice makes perfect
When the data are arranged in numerical order, the median is the middle value – or the mean of the two middle values – in a set of data.
Let's take a closer look at the given dataset.
9, 10, 12, x, 20, 25We have an even number of values, so the median is the average of two middle values.
Median: 12+ x/2
Finally, since we want the median to be 14, the above expression must equal 14. Let's write an equation for this and then solve for x.
